I have been dating my girlfriend, Michelle, for about four years and we are both twenty

I have been dating my girlfriend, Michelle, for about four years and we are both twenty. She has a younger sister who just turned eighteen. Carly is blonde, and has a real nice body with curves in all the right places. Much to the dismay of her sister and the rest of her family she likes to dress like a slut. The only underwear she owns are sexy thongs and boy shorts with sayings on them like “PINK” and “Sure Thing.” She always wears low cut tops that show her C cup cleavage and whenever she’s going out to party she wears really short skirts. Michelle dresses a lot more conservative than that so when I see how her sister dresses it really turns me on.

Michelle’s family had a reunion to go to out of town over the weekend. Her parents asked me if I would mind staying at their house that weekend to watch the house and take care of their dog. I agreed and figured it might be fun to go through Carly’s room while everyone is gone and look at her sexy underwear.

They were all set to leave when Carly throws a fit because one of her girlfriend’s is having her eighteenth birthday party on Friday night. Yes, Carly can be a real drama queen at times and like usual her parents gave in and let her stay home on the condition I agreed to watch her. They told me to make sure she doesn’t bring any boys home.

The rest of the family ended up leaving Friday around noon and they wouldn’t be home until late Sunday. At first I spent most of my time watching TV. I didn’t see much of Carly as she spent most of the afternoon in her room with the door closed. Finally, she started to get ready as I heard her going back and forth between the upstairs bathroom and her bedroom. I couldn’t wait to see what she put on because I knew whatever it was it was going to be extra sexy because her parents weren’t there to object to her outfit.

When I heard her coming down the stairs I rushed out into the hall pretending I needed to use the bathroom, but I really just wanted to get a good look at her. She was wearing a really short skirt and a top that showed a ton of cleavage. My cock got hard, but I am sure she didn’t notice as she never pays much attention to me. In fact in the past few months she had been unusually short and even somewhat bitchy towards me. I had asked Michelle about it and she just said it was just Carly being Carly and nothing for me to worry about.

“Hey, do you need to use the bathroom?” she asked.

“Yes, but if you need to use it first I can wait,” I replied.

When she went into the downstairs bathroom to give herself a final once over I called the dog over and started petting him. I positioned myself to make sure once she went back upstairs I would get an eye full. She comes out, I kept rubbing the dog and she starts back up the stairs. I am bent down so I can see right up her skirt. I could see her ass and her pussy barely covered by the little black thong she was wearing. I got a huge erection. I went back into the living room, sat on the couch and couldn’t wait for her to leave so I could beat off.

When she left I got some lotion out and start going to town thinking about what I had seen. God I wanted this little bitch bad even if she was my girlfriend’s sister. Plus, I was horny as hell as Michelle had cut way back on the sex over the course of the past few months. I came all over my belly, got up and cleaned up with some tissues. I watched TV for the rest of the night.

I went to bed in my girlfriend’s room at about 12:30 am. I wasn’t quite asleep yet when I heard her come in the front door downstairs as she was making a lot of noise. She was fumbling with the lock. By the time she got the door open I was fully awake. I heard her come in and shut the door behind her and kick her heels off. Then she slowly she ascended the stairs falling into the wall twice before she made it to the top. I laughed to myself realizing she was drunk.

Once she made it to the top of the stairs I heard her make a run for the bathroom. I hadn’t even heard the door shut when I heard her throw up.

BLAUAUAUAUauaaauuuuuauuuuu

BLAUAUAUAUauaaauuuuuauuuuu

BLAUAUAUAUauaaauuuuuauuuuu

This went on for several minutes, and I could hear her mumble to herself. After a few more minutes she quits throwing up. Then I heard her began to whimper and shortly this built into a full blown sob. I had heard enough so I got up and made my way to the bathroom. I didn’t even think to put anything else on I just went in my boxers and t-shirt.

The bathroom door was wide open. I found her on the floor in front of the toilet curled up in ball. She was covered with her own vomit shivering and crying. I noticed her thong on the floor. I realized she must have had it coming out of both ends and that was how her thong and the vomit ended up on the floor. She had been sitting on the toilet when she threw up. I looked down at her and could see her asshole and pussy sticking out beneath her short skirt.

She saw me come in and tried to say something. It was an awkward situation for her as she was deeply embarrassed that I was seeing her this way, but she didn’t want to be left alone and cold in a pile of her own puke for the rest of the night either. I just told her to lie still for a minute. I went out to the hall closet where the bath towels were and got a bunch of them. I was going to need them. I covered her up with one of them, put the rest of them on the vanity and went downstairs. I got some cleaning supplies, a couple of garbage bags and I fixed her a glass of sprite as it was the only clear drink I could find other than water. I went back upstairs and she was still under the towel shivering where I left at her. She didn’t try to say anything or get me to go away she just looked up at me and it seemed she was grateful I was there. I sat her drink and supplies down on the vanity.

I said, “ok in a second I am going to get you up so we can get you cleaned up, but first I need to know if you are done being sick yet?”

Faintly she replied, “….I don’t know.. I think I need to sit on the toilet, but I …. can’t get back up by myself.”

I knew I had to work quickly. I looked around and found the bathroom trashcan. I picked the towel I had thrown over her up and put it in one of the trash bags. I also put her dirty thong in there. I said, “ok I am going to pull you up, and we need to get the rest of your dirty clothes off quickly and then I am going to sit you down on the toilet.”

I looked at her for her consent to proceed with my plan and she nodded her head yes. I pulled her up, quickly lifted her top off and unclasped her bra. I pulled her skirt down, sat her on the toilet and handed her the trash can.

She was sitting there naked on the toilet holding the trash can and trying to avoid making eye contact with me. I picked up her soiled clothing and put them in the trash bag. I asked her, “what did you drink tonight?”

She replied weakly, “2/3rds a pint of cherry vodka.”

“Well that explains your predicament,” I said.

Nothing was happening on the toilet so I didn’t know if she was trying to hold back because I was in there or if she was over the worst of it.

I said, “look your drunk and embarrassed I get it so If you think your ok I can leave and go back to bed?”

I started to move like I was getting ready to vacate the room. She grabbed my arm and shook her head no.

I said, “ok now that I know you want my help you need to quit holding back if you need to go to the bathroom or puke just let it go and pretend that I am not here.”

She nodded her head yes.

She let go and pissed. Normally, I find the sound of girls peeing a real turn on, but I had dropped out of perv mode the minute I had walked into the bathroom and seen what kind of shape she was in. When she was done pissing she looked up at me and made a motion for the drink I had fixed her. I handed it to her and she took a drink and handed it back to me. She grabbed the trash can and put it up to her head.
